Actually, Alan is correct, as Ron also mentioned in the JSBSim-devel list, where this topic is cross-posted. I think it is quite possible that we can already do this using <function> definitions in the <aerodynamics> section of an aircraft spec. file. There is no perceptible performance hit to using <function> definitions. The functions are implemented in C++, are fairly efficient, and calculations are cached per-frame. I'd prefer not to see possibly type-specific hard-coded calculations going into the codebase - I think we can implement this in the current codebase using existing capabilities.
